Initial start-up and functions
8
Q-Factor
This control is used to adjust the Q factor (band-
width) of the Bass Boost. When set to “NAR” only a
narrow range around the center frequency (dened
by control 9) will be aected whereas when set to
“WIDE” the Bass Boost has a broadband eect
around the chosen center frequency. The Q factor
remains constant if the centre frequency (control 9)
is changed
.
9
Bass Boost Frequency
This control is used to adjust the center frequency
of the Bass Boost from 30 Hz to 80 Hz. The ad-
justed bass frequency can be enhanced from 0 to
12 dB with control 7.
This is useful to emphasize or correct a determined
frequency of the subwoofer (kickbass).
10
Subsonic
This control is used to adjust the crossover
frequency of the subsonic lter from 10 Hz to 50 Hz.
The subsonic lter cuts o very low frequencies
which aren’t audible and therefore relieves the am-
plier and also the subwoofer. Additionally the am-
plier will have more power available for the audible
frequencies. This control is always activated and its
adjustment is mandatory.
11
Lowpass
This control is used to adjust the crossover frequen-
cy of the lowpass lter from 50 Hz to 250 Hz. This
control is always activated and its adjustment is
mandatory.
In combination with the subsonic lter, the lowpass
lter creates a bandpass in any case. By adjusting
the subsonic (control 10) and lowpass lter (con-
trol 11) any bandpass between 10 Hz and 250 Hz
can be realized.
Caution: To avoid a loss of gain make sure that the
crossover frequencies of the subsonic and lowpass
lters do have an interval of at least two octaves
when generating a bandpass. That means if the
lowpass is adjusted to 100 Hz the subsonic should
be adjusted to 25 Hz or less (one octave = doubled
frequency or halved frequency).
